MACHINE FOR FELTING YARN.

SPECIFICATION forming part of Letters Patent No. 240,954, dated May 3,1881.

Application filed December 31, 1880. (No model.) Patented in FranceOctober 27, 1880.

To all whom it may concern:

Be it known that I, LOUIS BOURAU, of Paris, France, have invented a newand Improved Machine for Felting Yarns, of which the following is afull, clear, and exact description.

Heretofor the machines for making felted yarns 112M! {can constructedwith a taut cloth or linen sheet, upon which the yarns were felted, butit was impossible to give this sheet the desired tension. The operationwas very inconvenient and the yarns were stretched, thereby separatingthe filaments, which is just the reverse of that which is to be obtainedby felting the yarns.

The object of my invention is to provide a yarn-felting machine which issimple in construction, will felt the yarns without tension,

and complete the felting in a single operation.

The invention consists in a trough lined with felt and linen andprovided with a series of steam-pipes for heating it, in which trough acylinder rotates, which also has a longitudinal reciprocating movement,and is covered with felt and linen, between which cylinder and the innersurface of the trough the yarns to be felted pass, hot soap-waterspouting upon the cylinder during the operation.

In the accompanying drawings, Figure l is a longitudinal sectionalelevation of my im proved machine for felting yarns. Fig. 2 is a planView of the same.

Similar letters of reference indicate corresponding parts.

A cylinder, A, of wood or any other suitable material, is covered with alayer of felt, B, and over this a layer, 0, of linen is fastened. Thiscylinder A fits in a semi-cylindrical trough, D, the inner surface ofwhich is also covered with a layer of felt, E, over which a layer oflinen, F, is fastened, the cylinder A being journaled so as to revolvein this trough, with the surfaces of the cylinder and trough in contact.The trough D is provided with a series of pipes, G, through which steampasses to heat the trough, which is mounted above a tank, H, containinghot soap-water. A perforated tube, I, is arranged above the cylinder Aparallel to the same, and the hot soap-water that is taken from the tankH or some other suitable receptacle is forced through this tube andspouts through the openings of the same upon the cylinder A, as shown.The trough D is provided at the upper edge with overflow-pipes J, whichconduct the surplus of soap-water into the tank H.

The strands of yarn K to be felted are wound upon a cylinder, L, whichrests upon two rollers, M M, arranged a short distance from, and exactlyparallel with, the cylinder A. The yarn K then passes over adelivery-roller, N, from there between the cylinder A and trough D, thenpasses over a winged roller, 0, and is wound upon a reel, P, driven by abelt passing over the pulley Q of the same.

The shaft R of the cylinder A has abeltpulley, W, at one end, and at theother end it has a pulley, S, with angular groove T, into which a pin,V, on an arm fastened to the frame of the machine, passes. If thecylinder A is rotated it will be reciprocated longitudinally about fourto six inches as the pin V remains in the grooves T and the shaft Rrevolves; but I do not limit myself to this peculiar method ofreciprocating the cylinder A, but may use any other suitable devices forthis purpose. The belt-pulley must have a peg fitting into alongitudinal groove of the shaft B or some other suitable device, topermit the shaft to slide in the eye of the pulley.

The operation is as follows: The strands of yarn pass between thecylinder A and the trough D, as is shown and as has been stated 5 and asthis cylinder rotates, and has a reciprocating motion at the same time,it twists and felts the yarn, which is completely felted when it leavesthe trough. The hot soap-water is continually spouting upon thecylinder, as it is a very important factor in this process and makes thefibers and filaments very pliable, so that the felting will take placemuch more readily. The strands of yarn are not stretched, the operationis simple, and the yarn need not be operated upon several times insuccession, which is a great advantage, as each successive operationimpairs the results obtained by the previous one.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent l. A machine for felting yarn made as herein shown anddescribed, and consisting of a trough and a rotating and reciprocatingcylinder fitting; therein, between which cylinder and trough the yarn tobe felted is passed, as set forth.

2. In a machine for felting yarn, the combination, with the trough D andthe cylinder A fitting therein, of the layers of felt B and E,

and the coverings of linen O and F, substantially as herein shown anddescribed, and for the purpose set forth.

3. In a machine for felting yarn, the combination, with the cylinder Aand trough D, of the perforated water-tube I, substantially asWitnesses:
